Options
- Fe and Fe2O3
- Al and Al2O3
- Fe and Fe3O4
- Al and Al3O4
Explanation:
Here, the metal used in the thermite process is aluminium (Al). When aluminium is burned in air, it produces aluminium oxide (Al₂O₃), which is an amphoteric oxide.
So the correct option is (b) Al and Al₂O₃.
Here’s why the other options are incorrect:
- (a) Fe and Fe₂O₃: Iron (Fe) is not used in the thermite process. The thermite reaction uses aluminium and iron oxide (Fe₂O₃).
- (c) Fe and Fe₃O₄: As mentioned above, iron is not used in the thermite process.
- (d) Al and Al₃O₄: Aluminium oxide does not exist as Al₃O₄. The correct formula for aluminium oxide is Al₂O₃.
The thermite reaction is a highly exothermic reaction that produces a lot of heat.
It is used in welding, cutting, and demolition. The reaction is as follows:
2Al + Fe₂O₃ → Al₂O₃ + 2Fe + heat
In the reaction, aluminium is oxidized to aluminium oxide, and iron oxide is reduced to iron.
The heat released by the reaction is used to melt the iron, which can then be used to weld or cut metals.

An interesting discussion is worth comment. I do think that you should publish more
on this issue, it may not be a taboo subject but usually people do not speak
about such topics. To the next! All the best!!

Galera, vim dividir minhas impressoes no 4PlayBet Casino porque nao e so mais um cassino online. A variedade de jogos e muito completa: jogos ao vivo imersivos, todos bem otimizados ate no celular. O suporte foi rapido, responderam em minutos pelo chat, algo que raramente vi. Fiz saque em Ethereum e o dinheiro entrou em minutos, ponto fortissimo. Se tivesse que criticar, diria que seria legal torneios de slots, mas isso nao estraga a experiencia. No geral, o 4PlayBet Casino me conquistou. Ja virou parte da minha rotina.
